Specification Parameters Explanation

Depth Map resolution
Maximum number of rendered points (the resolution of camera sensor)
Point size
The average distance between two neighboring points on the point cloud of a plane located in the focus distance of the camera. Alternatively, the square of the point size is the average surface sampled by one 3D point on the plane scanned in the focus distance of the camera.
Relation of point size to scanning distance
Calibration accuracy
The accuracy of point measurement as the result of device calibration (can be understood as the space deformation). It is the standard deviation of the measurement error in the whole measurement range of the device.
Calibration accuracy is measured by scanning multiple planes at different distances from the scanner. Below you can see a scan of the plane done by the PhoXi 3D Scanner model S at the distance of 411mm. The red points are closer to the plane and the blue points are further away form the plane

Plane 2.png

Calibration accuracy is the average distance of the 3D points from this plane.


Temporal noise
The standard deviation of the noise (measured on a diffuse surface with 80 percent albedo). The noise level describes the quality of the sensor to capture local surface details. The noise distribution of our sensor is similar to the Gaussian distribution.
Below is a graph depicting the Standard deviation of depth (Z-noise) values of 3D points for different scanning distances for the PhoXi 3D Scanner model S.

Equivalently, Temporal noise can also be defined as the average distance of the 3D points from the average Z-value of the 3D points.
FPS
Maximum number of triggered frames per second, in fastest acquisition mode
Data acquisition time - best case
Fastest possible acquisition time
Data acquisition time - worst case
Longest expected acquisition time (bad lighting conditions, dark shiny objects)
3D points throughput
Number of 3D points that can be reconstructed in a second in sequential scans

Pinout

Power + GPIO Pinout

Power + GPIO port:

  • Use 12 VDC to power the scanner.
  • Use only the supplied power adapter.
  • The I/O ports are reserved for future use.

Ethernet Pinout

Ethernet port:

  • Powering the device through the ethernet port (PoE) is not possible.
  • Connect 1 Gbps ethernet adapter with RJ45 socket (supplied with scanner).
  • Use category Cat5e or better ethernet cables (cables capable of 1 Gbps or 10 Gbps transfer rate).

Maintenance

To preserve performance of PhoXi 3D Scanners and quality of the scans, please check and maintain their outer optical parts regularly. The glasses covering the camera unit and the projection should not be touched by bare hands to avoid staining of the glass. This could interfere with light passing through them. In case when the glass was touched or lightly stained by any other mechanism, wipe the glass with lint free wipes intended for optical components.

In cases where the scanner is used in an environment with lots of dust, especially when the dust contains sharp or hard particles that could potentially damage the glass, clean the glasses with specialized cleaning solution for optical components, eg: First Contact™ Cleaning Solution.

See Cleaning instructions for PhoXi 3D Scanners for further details about cleaning the scanners.
